He's finally aware of the affair his wife and brother had behind his back, and now, Jack (Peter Bergmann) is ready to blow their lives apart in the same way they did to him on The Young and the Restless.

After learning of the affair and storming out on Phyllis (Gina Tognoni) in anger, Jack let his frustrations about the situation slip while he did an interview on the Foundation with Neil (Kristoff St. John), and now, the entire world knows that Phyllis and Billy (Jason Thompson) slept together. And now, Phyllis at least is dealing with those consequences as she is hounded by reporters and rejected by her daughter, Summer (Hunter King), because of what she's done.

"C'mon Phyllis. Why did you sleep with your husband's brother?" A reporter asks her in a preview clip for the Monday, September 19 episode, as Summer looks on.

 But that won't be the end of the destruction Jack hopes to potentially reign on both Phyllis and Billy for betraying him so horribly. Not only will be swear to get back at them, but he will also inform Phyllis that he wants a divorce-news that will devastate her because she wanted to try and fix their marriage instead-and he wants her out of Jabot, meaning he could take away her life as she knows it completely.

Of course, those two won't be the only ones he targets for revenge, as he will quickly realize that Jill (Jess Walton) knew the truth and kept it from him, instead choosing to blackmail Phyllis into trying to end things and let him keep living a lie. Now, he will also confront her for her role in things playing out the way they now have, because he is livid she chose to try and find some way to protect Billy that kept her from being honest with him, and making him feel like a fool.

"I never meant for this to happen," she cries to him in the clip.

"Then why didn't you tell me?" He asks.

The Young and the Restless airs Monday-Friday at 12:30 p.m. on CBS.
